將json物件分離到不同的索引中-有解無憂

我有以下由 json 物件組成的陣列：

items = [
         {
           id: '1',
           name: 'Josh',
           transactionDate: '2012-08-10',
           creditAmount: '200',
           numberBank: '12345',
         },
         {
           id: '1',
           name: 'Josh',
           transactionDate: '2012-08-14',
           creditAmount: '159',
           numberBank: '12345',
         },
         {
           id: '1',
           name: 'Josh',
           transactionDate: '2012-08-15',
           creditAmount: '3421',
           numberBank: '12345',
         },
         {
           id: '2',
           name: 'George',
           transactionDate: '2012-09-15',
           creditAmount: '6000',
           numberBank: '13345',
         },
         {
           id: '2',
           name: 'George',
           transactionDate: '2012-09-16',
           creditAmount: '6565',
           numberBank: '13345',
         }
        ]

我想將每個相同的陣列索引分開id

舉個例子：

        [
         {
           id: '1',
           name: 'Josh',
           transactionDate: '2012-08-10',
           creditAmount: '200',
           numberBank: '12345',
         },
         {
           id: '1',
           name: 'Josh',
           transactionDate: '2012-08-14',
           creditAmount: '159',
           numberBank: '12345',
         },
         {
           id: '1',
           name: 'Josh',
           transactionDate: '2012-08-15',
           creditAmount: '3421',
           numberBank: '12345',
         }
        ],
        [
         {
           id: '2',
           name: 'George',
           transactionDate: '2012-09-15',
           creditAmount: '6000',
           numberBank: '13345',
         },
         {
           id: '2',
           name: 'George',
           transactionDate: '2012-09-16',
           creditAmount: '6565',
           numberBank: '13345',
         }
        ]

該怎么做？謝謝

uj5u.com熱心網友回復：

您可以使用reduce分組依據id，然后使用結果的值Object.values

let items = [
         {
           id: '1',
           name: 'Josh',
           transactionDate: '2012-08-10',
           creditAmount: '200',
           numberBank: '12345',
         },
         {
           id: '1',
           name: 'Josh',
           transactionDate: '2012-08-14',
           creditAmount: '159',
           numberBank: '12345',
         },
         {
           id: '1',
           name: 'Josh',
           transactionDate: '2012-08-15',
           creditAmount: '3421',
           numberBank: '12345',
         },
         {
           id: '2',
           name: 'George',
           transactionDate: '2012-09-15',
           creditAmount: '6000',
           numberBank: '13345',
         },
         {
           id: '2',
           name: 'George',
           transactionDate: '2012-09-16',
           creditAmount: '6565',
           numberBank: '13345',
         }
        ]
        
let res = Object.values(items.reduce((acc,curr)=> {
    if(!acc[curr.id])acc[curr.id]=[]
  acc[curr.id].push(curr)
  return acc
},{}))

console.log(res)
